I also have the logo issue.
A I can’t see a fix from the developer yet, I recomment in the meantime making an arrangement to the logo image. Just make a new png file adding blank canvas above and below (double as the sole image), and now it is acxceptable.
It must be some css issue on the image height (borders, limits…)
If anyone expert in css can fix the problem or tell the developer, it would be nice.
